Mr. Pete, you were born to teach. I notice that you repeat the names of all the parts as you explain the process so people learn the names at the same time. You show the importance of math also. We used to ask “why do we need to know all this math when we won’t use it”. I really enjoy watching you teach and I wonder how many thousands of young men learned how to make and fix things sitting in your classroom/shop at school. Keep it up!
God bless you shop teachers... You all have a lot more patience than I do, and I think your classes save lives when it comes to giving kids an option besides a four year degree, or a dead end minimum wage job. Great vids, BTW.
I have made gears and found this video very helpful. Thanks for the help! You're fun to watch. I'd like to boast I've watched all your videos but I figured out if I watched 24 hours a day it would take way too long to watch them all in what's left of my life.
Thank you for taking the time to share your impressive skill set and knowledge. I don't come from any machining/engineering background (none in my family either) but I find all this stuff fascinating and maybe one day I'll come to own my own small metal workshop and start learning how to do metal work.
ARE YOU KIDDING? KNOW that at least one viewer IS ACTUALLY GOING TO DO THIS !!! I have to make up all the gears in the feed gearbox on a small Colchester lathe I recently bought. It came from a school where pupils used the boot to change gears on the feed gearbox, broke one of the selectors (which left it in a gear) and then put it into all the other gears using the other selector (and of course the boot). You know what engaging 2 gears at the same time WHILE IN MOTION does to a gearbox? Thats right - it strips all the gears (especially when the machine is running and a student a$$hole kicks it into gear) and now all that is left is a bunch of gears with no teeth. Then all the broken teeth damaged all the other teeth - a nice mess. The guy I bought it from told me "the feed box is full of gums" - he was right, NO TEETH, just stubs but I think there are enough remains to figure out what they were. I also have a small Chinese "Lathe/Mill" and fortunately a small dividing head (brand new WITH all the plates) as well so I will be doing it on that but as I am a pensioner and do not have the funds to buy the cutters I will need so I will have to use the method you demonstrated in the rack cutting video (fly cutter with single tool steel cutter) Here is a question : How do I sharpen/profile a toolsteel tool tool at home with VERY limited resources? Any suggestions? I will probably have to make up some tools (keysteel with a tungsten slug braised onto it) and if I can find the appropriate profile gauges, do it by hand or get them professionally profiled and sharpened and work VERY CAREFULLY with them. To be honest, if the end result is a gearbox that is somewhat noisy then that is fine, as long as each gear tooth is equally noisy then it should not affect the work piece that is being cut (thread or whatever) afterwards. The gearbox is not "high speed" nor is it a very hard working (high forces being transmitted) environment it lives in so I think that it is totally do-able. The price of tooling here (Johannesburg, South Africa) is ridiculously high and buying online the shipping costs are anything up to 10 times the purchase price, sometimes more, so "going old school" is the only way. I am a qualified artisan (automotive machinist and fitter, fitter and turner, millwright) but have not worked in the trade for over 30 years and am therefore somewhat rusty but when I am watching your videos, every one has at lest one "Oh Yes, I remember that" moment. So do not think that your videos are simply "entertainment" - reading some of the comments I see that you are influencing younger people in their career choices and that is a very good thing - otherwise the trade and all the knowledge gets lost forever - NOT GOOD for humanity. Great videos and please keep them coming and all the best to you.
Now I have a few cutters, made an arbor and cut some teeth. It was a random scrap of Nylon so the dimensions aren't correct and it doesn't mesh correctly, but I can probably cut gears now. I'll have to improve the arbor and get some more stock and maybe I'll get to make some that work.
@@mrpete222 yes I don't think that I think you about that fly cutter idea either I did that for repairing a bull gear and it worked perfectly. I did it a little unconventionally I milled a slot where the three broken teeth were took a pizza cast iron and shaped it perfectly to match the original diameter and brazed it into place. I did not have the dividing head at that time so I put it in a spin indexer and in a CAD program recreated the exact layout of the gear include it on to the side of the gear so it lined up with all the existing teeth. Then I just matched up the fly cutter exactly with the printed template and cut the teeth and it worked absolutely perfectly other than the breeze wine you cannot tell the difference it is absolutely flawless. It just goes to show you when there is a will there is a way. It may not be a perfect solution but if it gets you going it is a good solution. And I owe it all to you. I know I've probably told you this before but I am badly disabled when I say badly I mean it. I'm also getting on in years so what's up this Hobby I would be sitting staring at a TV day in and day out and showing no productivity at all which is the death of anyone. I recently had to sell my hardinge lathe after I got it tooled up to the max! I even had a nice threading head with every chaser known to man. Unfortunately I had no choice I needed the money. Being disabled does not pay much LOL now I'm looking for a nice big leblond or other Gear Head lathe so I can get back to my hobby of making Cannon.

I've been looking for a mic like that for years I love it I might have seen it in one of your videos the first time and I've wanted one ever since as a matter of fact I think it was one of yours it's so easy to read and my eyes ain't what they used to be
I don’t know if someone has already commented on this, but semi steel is indeed cast iron. But there’s a twist. They throw some steel scrap into the mix. That was how it was made back in the old days. More recently, instead of the random way they used to do it, it’s more regularized, though not standardized. Operationally, it’s not much different from cast iron. But it has a bit finer grain, and is a bit more ductile. Just think of it as cast iron, between grey and ductile.
Thank's again Mr.Pete.My shop is tiny,so all my projects are small,but I really enjoy your videos and am finding it's possible to teach an old dog(*me) new tricks in my retirement
I have never used a lathe or milling machine but found your video very interesting to watch. Thank you for taking the time to explain these things that people like myself would almost certainly never see otherwise.
Your timing is excellent. A friend and I are preparing to make a gear for his Logan 820 lathe. We are building an electronic dividing head with a CNC stepper motor and Arduino controller. There are a number of these demonstrated on TH-cam. Your videos are ALL fun for me to watch, but the gear cutting series has been particularly relevant. Don't think for a moment that your videos are only entertainment. They are truly educational and directly helpful. Thank you!
Once again, wonderful video. A long - long time ago I worked in a foundry with a cupola in it. We made semi steel by replacing every fourth load of pig iron with carbon steel scrap. That brought the carbon down a bit & made the castings a little tougher.
I have to say I have Learned more from your videos then I did in school and in welding class I thank you for taking the time to make these incredible videos and for sharing them with the world you're a pretty awesome guy have a bless day
you are just a good man and I like what you are doing to help someone like me who are trying to learn much more about this knowledge thank you and I appreciate your time and your passion..........
I sure could use that gear!!! Just got one of these Logan 200 Lathes from the original owner and on of the extra gears is broken!!! Can you guess which one? You got it the 24 tooth!!! Lol!!! Keep Rocking it out!!!
Hmmm, I don't have a Logan lathe, dividing head, mill, or any of the many other things that were used here. But I do have another bit of information packed in my brain to amaze and amuse my friends when I mention an involute cutter needed to make a gear for the Logan lathe. Great video Mr. Pete, if I did have all of the above I would be in my shop tomorrow morning to try my hand at it.
Let's see. Watching a 5 year old vid, I've got a SBL born Dec, 1941, and that, and most of my tooling/fixturing is older than me (60+yrs). I'm lovin' me some Mr. Pete! Good stuff.
Thanks Pete, I truly appreciate your clarity. It seems I have a terrible job ahead of me. I need to build a 1*1 bidirectional multi-gear assembly. It is totally in my head at this point so it looks like I better get out the paper for this concept to become real. Lots of thinking ahead of me. I'll have to look into your other videos to see if there is something I can use.
Hi mrpete, Unless we specialize in gear cutting, it's not everyday I cut gears, so, every time I have to cut one, there is always the reading cession before the task... This is a super nice memory refreshment of the whole complete process... Thanks again, Pierre
pierre beaudry The 10,000 probably does not include the gas to go to every swap meet in the area to find the gear, Or the time to rebuild it when you get it......or the cost of buying things twice because the first used one was fubared.....
We may be wrong here, i just checked my local craigslist and there is a K&T mill for 3000 vancouver.craigslist.ca/rds/hvo/4959522404.html As well as a single lot of what looks like EVERY gear cutter and some milling/slotting cutters for $2700 vancouver.craigslist.ca/rds/tls/4951415968.html So that is machine and cutters for 5700 Canadian. Dividing head and arbors shouldn't be 4500 bux.....
I'm in Canada, and I'm not dividing... If you want to see how little place there is and how packed it is, you're welcome to take a look at my channel. Cheers, Pierre
Great video Mr. Pete. I am in fact assembling the bits and pieces to make my own $10K gears for my $500 lathes. It's a slow process. Whenever I get all the pieces together, I will refer back to this video. Thanks for posting.
You’ve just earned my subscription! I have already purchased a Chinese mini lathe (for practice and I was only planning on making rings) and I’m already regretting it. It’s pretty much worthless and I should have stuck with my guns with the Buy once, cry once mentality and shelled out the extra cash for a good one. Watching this video just fired up that burning desire of “I want to do that!!!” I’ll be keeping my eyes peeled for a lathe/mill combo when I replenish the account and I’m not settling for anything but quality. I’m just imagining the possibilities already.
Wikipedia: Semi-steel casting is a lower cost method to produce a casting that is not quite as strong as a steel casting but less expensive to manufacture. It was used more commonly as a marketing term. The carbon and silicon percentages are reduced to the amount approximately consistent with those in steel. This is done using pig iron or gray iron casting scrap and reducing the amount of carbon through the addition of relatively pure steel or wrought iron scrap in a well heated cupola furnace. The percentage of carbon is typically between foundry cast iron and wrought iron.
Brian Taylor - Thanks for this information. I would like to ask Scott Logan about his memories of his Dad’s (Logan Lathe’s) gear manufacturing, back in the day, from casting to final milling. I guess I’m just an old industrial history nut. Roy Lewis 1946 Logan 825 10” Lathe See. No. 34503
We, in the UK went metric decades ago. I was apprenticed as a toolmaker in the late 60s and worked in thousandths of an inch. It's refreshing that I know exactly what you are talking about in terms of inches, rather than millimetres, although to be honest, I can now work in either system seamlessly. In those days we were in a transitional period in the UK, whereby the drawing office were still working in inches but translated dimensions into millimetres (mm) on the drawings. All the machines in the Tool Room machine section were old American (Bridgeport or Cincinnati) or British machines (Dean, Smith and Grace, Myford, Boxford, etc) and the indexing dials were all in imperial inches... so you see where I'm coming from here... 1) Draughtsman designs in Imperial inches then converts to metric mm (ISO) 2) Tool Room receives drawings in metric and is unable to use them in this state since none of the machinery handles mm ISO units. 3) All drawings go to the marking bench, to have them converted back into Imperial inches. 4) Sometimes things went slightly wrong - lost in translation! Thank you for speaking to me in inches!
Hi mr pete, Well made video. The shop i work at we cut gears on a horizontal mill. Basically the same setup but the cutter is at the top of the gear blank. Thank you for the videos, even us guys you work in the machining trade can learn from you. Jeff Miller
Yep, that's us. $10,000 worth of equipment to make a $50.00 gear so we can use the $10,000 worth of equipment to fix the $300.00 lawnmower. Thanks, Mr Pete, for the video and the humor. John
For those of us with an old lathe, missing a change gear, who don't have the mill, dividing head, or tooling, I have considered the following options... 1. Print out paper template, glue to steel, drill rough, hacksaw near line, file to the line 2. Grind HSS tool bit to the right shape, and manually run lathe like a shaper to cut each tooth (maybe combine with step 1 to reduce amount of metal to shape) - indexing with big paper template, locking spindle somehow... 3. Waterjet or laser cut? Not sure if this can go thick enough without taper effecting the cut, or file finish?
Many thanks, very interesting. Joke, A Yorkshireman on an exchange visit to a German machine shop,.. The German host describes how the machine is accurate to within 1000th of a millimetre, the Yorkshireman replies," That would be no good back home, we need to be spot on" I am sure the joke would translate to various US states,obviously in Thousandths of an inch.
Semi-Steel is a casting method that is less expensive than casting regular steel. Is done by mixing grey or pig iron with regular steel to reduce the carbon content of the iron.
As a young lad my father apprenticed (110 years ago) in the drafting rooms of American Locomotive at their Paterson (NJ) works, he later went on to other things (that was good since ALCO went out of business) but never lost his skills at the table. His sketches of locomotive parts and his lifelong interest in steam locomotives was passed on to me along with an appreciation of the skills involved in building these great beasts. A couple of years ago I rode the Grand Canyon railroad and they had a beautiful locomotive, I checked the builders plate, it was an ALCO made at Paterson during my father's time, maybe he did some of the drawings for it? We in the west are at great risk of losing our mother tool industry (the tooling that makes the tools used in industry), we might have already done so, the Japanese still have theirs and the Chinese are developing (they lack the concept of quality that is now fundamental to the Japanese), the Brits lost theirs under socialism. There might be some life left in Europe's big three Germany, Italy, and France. Point is if you want to build a steel mill in the US, you go to Japan and buy the parts, there is no Mesta machine works in Pittsburgh anymore. The last thing we are now losing is the skilled craftsmen of the metal trades, our totally messed up socialist leaning education system no long provides a path in this direction for student who might want to go there. Thank you for making some of this training available in a format usable by the young generation and maybe in a way providing a historical record. Please encourage others with your skills do at least some of that you are doing, you even could possible provide the video skill for some of your machinist friends who don't. It is very encouraging that you don't use any of the 'new math' that is computationally extremely slow and cumbersome. Please continue this great work!
That is a great story about your grandfather. Everything is so true that you said about industry in the great USA. And of course that saddens me. Your analysis, impressed me enough to where I am going to show your comment in its entirety in my next this in that video. Thank you
My father, I'm probably older than you. My pilot's license is still current thought! By the way, though I love the steam engines, the railroads choice of going diesel is and was the correct one. Diesels have three time the fuel efficiency and probably ten time the labor efficiency of the old chochos. The economics of pure electrics such as the europeans use doesn't include the tremendous fixed investment in the overhead distribution system, the maintenance of that and the line losses involved.
@@mrpete222 About 25 years ago, my brother in law, who was the operations VP of the National Steel Co. of the Philippines came to Pittsburgh to buy an old steel rolling mill that had been closed (heck, trees were growing thru the roof!) when word got out of this impending purchase, the then governor of PA, a fellow named Casey, (his son is the Senator) came to town with his soapbox and gave a chest thumping speech about no mills leave PA during his watch. The selling parties sent him a letter appreciating that he had matched the sale offer my brother in law made, Casey took the first train out of town. The mill was in pretty bad shape, and Mesta Machine Works was long gone (remember Lyndon Johnson's friend Pearl Mesta, hostess with the most-est, that was were her money came from) and there was no firm in the US that could redo the tooling. He found a firm in Japan that could, the mill was disassembled and shipped downriver to New Orleans and from there to Japan. He said when the Japs were done with the rollers they looked like mirrors. The program was a success, the mill rolled out sheet steel for cans and tin roofs, widely used there. He eventually retired as Executive VP of the company. Some years later, my son was at Law School in Pittsburgh, he took us out to lunch at a new shopping center, the former US Steel Homestead Works, the architectural feature of the center was all the big ladels and other tooling of the mill. I couldn't help feeling that the waitress who served us probably had a grandfather who worked at that mill and he probably made more money than she did and back when money was worth something.
Stripping all the gears in an old lathe in shop class is just the beginning of a career. Next we will work on stripping all the gears in our first car and go on from there. Lots of fun. Sooner or later we realize it is getting expensive for somebody and now that somebody is me. Now I'm full circle in my job as a machinist making gears to replace someone else's stripped gears. Ain't life funny? (Yeah, as long as somebody else is paying for it)
Thank you for this video. I may have an opportunity to work with an Atlas lathe at a museum i want to volunteer at and found this video very informative.
"Always count numbers out loud"...I thought I was the only one that does this. My boss thinks I'm weird but if you have to walk across the room or climb down a ladder and you have 3 guys in the room talking about beer and chicken wings then saying it out loud makes all the difference between a finished product or scrap. Obviously if it's really important I can write it down, but over the course of the day you can lose a lot of time drawing pictures and writing numbers... bosses don't like that. I love your videos, I have watched almost all of them, they are like "engineer porn". (LOL). I am building a lathe and I am almost done....I am waiting on my 5 inch chuck to come in the mail. Your videos have taught me a lot....mostly about thinking "smarter, not harder". Thank you!
when i was young and before i learned the right way to make gears i would trace a tooth from a gear .... hold a piece of paper to the tooth and make a rubbing with pencil or literally trace it... or xerox them.... i would cut the paper with a xacto glue to my blank then grind a cutter to fit with no light shining thru.... works great and i still do it that way unless i do not have a gear to copy
Wow, that was another great one. Watching these videos has really helped me with my career choices. I would most certainly be able to do the math, just not 8n a typical Vocational education setting.
You prolly dont care at all but does anybody know a method to get back into an instagram account? I somehow lost my account password. I love any assistance you can give me.
@Avery Cayden i really appreciate your reply. I got to the site through google and Im in the hacking process atm. Looks like it's gonna take quite some time so I will get back to you later with my results.
Only piece of advise you left out is to make sure you wind the dividing head in the working direction to the first position to avoid the dreaded thin/thick tooth on the last cut, otherwise a fantastic and concise tutorial.
Great video I try and follow along 1-2 steps ahead to see if I get it correct on what and how the next step is done about 1/4 of the time I get it wrong lol but I am getting better! Looking forward to the next video and as always Thank you for taking the time- I really appreciate all that you do I have learned so much
Point of interest here, from the future lol. If you're buying cheap chinesium gear cutters like myself, they normally have the numbering system backwards. Meaning, a chinese DP16 14-1/2PA number 1 cutter will cut a 12 to 13 tooth gear, and so on. I don't know why this is the case, but i've found it to be true 100% percent of the time in my experience, which is very limited, but there you have it.
Mr. Pete, I mean no disrespect, but isn't 660 RPM way too fast for that cutter in steel? Mild steel should be cut around 100 SFPM or so, and with a cutter of 2.5" in diameter, that should be about 150 RPM. Or am I missing something?
lyle i mean... i dont know if you read this but I own a mini lathe for 3 months now and i'm about to build a real milling machine... i got the head and the knee almost completed and now i need to make a drive to couple my 1 hp induction motor to the spindle. i really want to use gears since its the most exact and the method with that i can put all the torque into the spindle, now i watch your video and i hope that after that i can make a set of gears that will fit (not a rich guy sadly :D ) so maybe you become part of my homebrew machine :)
This is so much easier than my process of single point gear broaching on my lathe. You could single point broach the keyway on the mill or lathe with a HSS bit.
I realize that this is a 7+ year old video (and I really enjoyed it), but at the 32 minute mark, where you're all finished cutting the gear and then remove the lathe dog and then the mandrel I wondered WHY?! I thought for sure you'd be taking the assembly back over to the lathe to do a final skim pass (and chamfer if you hadn't already) on both sides to clean them up. Seems that would be easier prettier than the belt sanding you suggest in the video, no? But again, I really enjoyed the video, and subscribed quite a while ago.
I enjoyed the video. Just one thought. after you find that you need 1/6th a turn on your turn wheel. you just need to find a plate that is dividable by 6. so a plate with 6, 12, 18, 24, 30, 36, etc
Random guess: "Semi-steel" may mean that it was cast iron which was then steeled. You can do things like let it bake in a pile of charcoal until the carbon penetrates the outer layers, making a hard layer of steel around the iron core. It's easy, cheap and probably much faster to do in bulk at the time. Of course, I could also be completely wrong.
I know this is a stupid question but I'm finally getting around to doing this tomorrow so I noticed there's nine spaces in your 48 hole circle between dividing arms. So is that mean it's 9:00 because the first one is your first cut and then you move eight more and advance the arms?. I know this will be obvious to a lot of people but I'm very nervous
I have a montgomery wards 04tlc-700a that rattles something bad when running, what would you think it is. The rattle is coming from head stock at the bull gear.
I did know (and love) Keith Rucker. Yet I didn't know about Keith Fenner. Thank you for that! TH-cam, more than half of what I watch is related to manual-operated machinery. Is it really so hard to figure this out and actually recommend popular channels like this that I don't know about? Sorry, I'm ranting, please ignore me.

Thats right - it strips all the gears (especially when the machine is running and a student a$$hole kicks it into gear) and now all that is left is a bunch of gears with no teeth.
Then all the broken teeth damaged all the other teeth - a nice mess.
The guy I bought it from told me "the feed box is full of gums" - he was right, NO TEETH, just stubs but I think there are enough remains to figure out what they were.
I also have a small Chinese "Lathe/Mill" and fortunately a small dividing head (brand new WITH all the plates) as well so I will be doing it on that but as I am a pensioner and do not have the funds to buy the cutters I will need so I will have to use the method you demonstrated in the rack cutting video (fly cutter with single tool steel cutter)
Here is a question : How do I sharpen/profile a toolsteel tool tool at home with VERY limited resources?
Any suggestions?
I will probably have to make up some tools (keysteel with a tungsten slug braised onto it) and if I can find the appropriate profile gauges, do it by hand or get them professionally profiled and sharpened and work VERY CAREFULLY with them.
To be honest, if the end result is a gearbox that is somewhat noisy then that is fine, as long as each gear tooth is equally noisy then it should not affect the work piece that is being cut (thread or whatever) afterwards.
The gearbox is not "high speed" nor is it a very hard working (high forces being transmitted) environment it lives in so I think that it is totally do-able.
The price of tooling here (Johannesburg, South Africa) is ridiculously high and buying online the shipping costs are anything up to 10 times the purchase price, sometimes more, so "going old school" is the only way.

Once again, wonderful video. A long - long time ago I worked in a foundry with a cupola in it. We made semi steel by replacing every fourth load of pig iron with carbon steel scrap. That brought the carbon down a bit & made the castings a little tougher.
Metallurg33 Thanks for watching
I have to say I have Learned more from your videos then I did in school and in welding class I thank you for taking the time to make these incredible videos and for sharing them with the world you're a pretty awesome guy have a bless day
New Generation THANKS for watching
you are just a good man and I like what you are doing to help someone like me who are trying to learn much more about this knowledge
thank you and I appreciate your time and your passion..........
I sure could use that gear!!! Just got one of these Logan 200 Lathes from the original owner and on of the extra gears is broken!!! Can you guess which one? You got it the 24 tooth!!! Lol!!!
Keep Rocking it out!!!
Yes
Hmmm, I don't have a Logan lathe, dividing head, mill, or any of the many other things that were used here. But I do have another bit of information packed in my brain to amaze and amuse my friends when I mention an involute cutter needed to make a gear for the Logan lathe. Great video Mr. Pete, if I did have all of the above I would be in my shop tomorrow morning to try my hand at it.
👍👍
Let's see. Watching a 5 year old vid, I've got a SBL born Dec, 1941, and that, and most of my tooling/fixturing is older than me (60+yrs). I'm lovin' me some Mr. Pete! Good stuff.
👌👌
I watch your videos because they are interesting. The necessary tools are a bit out of my budget, but it's still fun to watch people create things.
***** Thanks for watching
Thanks Pete, I truly appreciate your clarity. It seems I have a terrible job ahead of me. I need to build a 1*1 bidirectional multi-gear assembly. It is totally in my head at this point so it looks like I better get out the paper for this concept to become real. Lots of thinking ahead of me. I'll have to look into your other videos to see if there is something I can use.
Hi mrpete,
Unless we specialize in gear cutting, it's not everyday I cut gears, so, every time I have to cut one, there is always the reading cession before the task...
This is a super nice memory refreshment of the whole complete process...
Thanks again,
Pierre
pierre beaudry BTW, If it only cost you $10,000, to get fully tooled, tell me where to get such a great deal... lol
pierre beaudry The 10,000 probably does not include the gas to go to every swap meet in the area to find the gear, Or the time to rebuild it when you get it......or the cost of buying things twice because the first used one was fubared.....
I know, I'm pretty well stocked and I can't tell how much I've spent so far, many, many times the $10k...
We may be wrong here, i just checked my local craigslist and there is a K&T mill for 3000
vancouver.craigslist.ca/rds/hvo/4959522404.html
As well as a single lot of what looks like EVERY gear cutter and some milling/slotting cutters for $2700
vancouver.craigslist.ca/rds/tls/4951415968.html
So that is machine and cutters for 5700 Canadian. Dividing head and arbors shouldn't be 4500 bux.....
I'm in Canada, and I'm not dividing... If you want to see how little place there is and how packed it is, you're welcome to take a look at my channel. Cheers, Pierre
Great video Mr. Pete. I am in fact assembling the bits and pieces to make my own $10K gears for my $500 lathes. It's a slow process. Whenever I get all the pieces together, I will refer back to this video. Thanks for posting.
Rick Rose Thanks for watching
Mr Pete I absolutely enjoy your videos. Thank you for your effort

Always informative and fun to watch!
You’ve just earned my subscription!
I have already purchased a Chinese mini lathe (for practice and I was only planning on making rings) and I’m already regretting it. It’s pretty much worthless and I should have stuck with my guns with the Buy once, cry once mentality and shelled out the extra cash for a good one. Watching this video just fired up that burning desire of “I want to do that!!!”
I’ll be keeping my eyes peeled for a lathe/mill combo when I replenish the account and I’m not settling for anything but quality.
I’m just imagining the possibilities already.
Bigger is better
Wikipedia: Semi-steel casting is a lower cost method to produce a casting that is not quite as strong as a steel casting but less expensive to manufacture. It was used more commonly as a marketing term. The carbon and silicon percentages are reduced to the amount approximately consistent with those in steel. This is done using pig iron or gray iron casting scrap and reducing the amount of carbon through the addition of relatively pure steel or wrought iron scrap in a well heated cupola furnace. The percentage of carbon is typically between foundry cast iron and wrought iron.
Brian Taylor Thanks for watching
Brian Taylor Thank you Brian.
Brian Taylor - Thanks for this information. I would like to ask Scott Logan about his memories of his Dad’s (Logan Lathe’s) gear manufacturing, back in the day, from casting to final milling.
I guess I’m just an old industrial history nut.

We, in the UK went metric decades ago. I was apprenticed as a toolmaker in the late 60s and worked in thousandths of an inch. It's refreshing that I know exactly what you are talking about in terms of inches, rather than millimetres, although to be honest, I can now work in either system seamlessly.
In those days we were in a transitional period in the UK, whereby the drawing office were still working in inches but translated dimensions into millimetres (mm) on the drawings. All the machines in the Tool Room machine section were old American (Bridgeport or Cincinnati) or British machines (Dean, Smith and Grace, Myford, Boxford, etc) and the indexing dials were all in imperial inches... so you see where I'm coming from here...
1) Draughtsman designs in Imperial inches then converts to metric mm (ISO)
2) Tool Room receives drawings in metric and is unable to use them in this state since none of the machinery handles mm ISO units.
3) All drawings go to the marking bench, to have them converted back into Imperial inches.
4) Sometimes things went slightly wrong - lost in translation!
Thank you for speaking to me in inches!
+Gordon Burns We went thru that here also. They called it a soft conversion.
Hi mr pete,
Well made video.
The shop i work at we cut gears on a horizontal mill.
Basically the same setup but the cutter is at the top of the gear blank.
Thank you for the videos, even us guys you work in the machining trade can learn from you.
Jeff Miller
Jeffrey Miller Thanks for watching
It’s my dream to one day be able to do this with no problem
Yep, that's us.
$10,000 worth of equipment to make a $50.00 gear so we can use the $10,000 worth of equipment to fix the $300.00 lawnmower.
Thanks, Mr Pete, for the video and the humor.
John
John Bazaar Ha Ha- suckers. I only spent $9,997.79! Ya gotta know how to haggle! :)
The best video I've seen yet on this subject!!
I need to learn how to find those auctions ........ I have no idea
Having a $300 lawnmower that works is better than having a $300 pile of junk that takes up space.
Always excellent video and very informative. I appreciate your time and relaxed demeanor in teaching us these valuable skills.
Jeff Barr Thanks for watching
Very quick and concise process!
WAVETUBE84 Thanks for watching
For those of us with an old lathe, missing a change gear, who don't have the mill, dividing head, or tooling, I have considered the following options...
1. Print out paper template, glue to steel, drill rough, hacksaw near line, file to the line
2. Grind HSS tool bit to the right shape, and manually run lathe like a shaper to cut each tooth (maybe combine with step 1 to reduce amount of metal to shape) - indexing with big paper template, locking spindle somehow...
3. Waterjet or laser cut? Not sure if this can go thick enough without taper effecting the cut, or file finish?
You're a very skilled gentleman Mrpete.
+Oliver Ehmann thanks for watching
Love listening to these old timers pass on knowledge, I would love to sit and learn from this man.
Thanks
G'day Kevin here from Australia.
being new to lathes and one of your subscribers l stumbled on another excellent video from you. A+
thanks
Thanks for sharing that video. Very nice job on the gear.
Fred German Thanks
Many thanks, very interesting.
Joke, A Yorkshireman on an exchange visit to a German machine shop,.. The German host describes how the machine is accurate to within 1000th of a millimetre, the Yorkshireman replies," That would be no good back home, we need to be spot on"
I am sure the joke would translate to various US states,obviously in Thousandths of an inch.
It was a great joke. Had me laughing all afternoon!
We convert Metric jokes to Imperial jokes all the time by simply multiplying them by 25.4, and back the other way by dividing them by 25.4
Semi-Steel is a casting method that is less expensive than casting regular steel. Is done by mixing grey or pig iron with regular steel to reduce the carbon content of the iron.
Thanks
As a young lad my father apprenticed (110 years ago) in the drafting rooms of American Locomotive at their Paterson (NJ) works, he later went on to other things (that was good since ALCO went out of business) but never lost his skills at the table. His sketches of locomotive parts and his lifelong interest in steam locomotives was passed on to me along with an appreciation of the skills involved in building these great beasts. A couple of years ago I rode the Grand Canyon railroad and they had a beautiful locomotive, I checked the builders plate, it was an ALCO made at Paterson during my father's time, maybe he did some of the drawings for it?
We in the west are at great risk of losing our mother tool industry (the tooling that makes the tools used in industry), we might have already done so, the Japanese still have theirs and the Chinese are developing (they lack the concept of quality that is now fundamental to the Japanese), the Brits lost theirs under socialism. There might be some life left in Europe's big three Germany, Italy, and France. Point is if you want to build a steel mill in the US, you go to Japan and buy the parts, there is no Mesta machine works in Pittsburgh anymore. The last thing we are now losing is the skilled craftsmen of the metal trades, our totally messed up socialist leaning education system no long provides a path in this direction for student who might want to go there. Thank you for making some of this training available in a format usable by the young generation and maybe in a way providing a historical record. Please encourage others with your skills do at least some of that you are doing, you even could possible provide the video skill for some of your machinist friends who don't. It is very encouraging that you don't use any of the 'new math' that is computationally extremely slow and cumbersome.
Please continue this great work!
That is a great story about your grandfather. Everything is so true that you said about industry in the great USA. And of course that saddens me. Your analysis, impressed me enough to where I am going to show your comment in its entirety in my next this in that video. Thank you
My father, I'm probably older than you. My pilot's license is still current thought! By the way, though I love the steam engines, the railroads choice of going diesel is and was the correct one. Diesels have three time the fuel efficiency and probably ten time the labor efficiency of the old chochos. The economics of pure electrics such as the europeans use doesn't include the tremendous fixed investment in the overhead distribution system, the maintenance of that and the line losses involved.
@@mrpete222 About 25 years ago, my brother in law, who was the operations VP of the National Steel Co. of the Philippines came to Pittsburgh to buy an old steel rolling mill that had been closed (heck, trees were growing thru the roof!) when word got out of this impending purchase, the then governor of PA, a fellow named Casey, (his son is the Senator) came to town with his soapbox and gave a chest thumping speech about no mills leave PA during his watch. The selling parties sent him a letter appreciating that he had matched the sale offer my brother in law made, Casey took the first train out of town. The mill was in pretty bad shape, and Mesta Machine Works was long gone (remember Lyndon Johnson's friend Pearl Mesta, hostess with the most-est, that was were her money came from) and there was no firm in the US that could redo the tooling. He found a firm in Japan that could, the mill was disassembled and shipped downriver to New Orleans and from there to Japan. He said when the Japs were done with the rollers they looked like mirrors. The program was a success, the mill rolled out sheet steel for cans and tin roofs, widely used there. He eventually retired as Executive VP of the company.
Some years later, my son was at Law School in Pittsburgh, he took us out to lunch at a new shopping center, the former US Steel Homestead Works, the architectural feature of the center was all the big ladels and other tooling of the mill. I couldn't help feeling that the waitress who served us probably had a grandfather who worked at that mill and he probably made more money than she did and back when money was worth something.
Thank you for your time in sharing your expertise.

Stripping all the gears in an old lathe in shop class is just the beginning of a career. Next we will work on stripping all the gears in our first car and go on from there. Lots of fun. Sooner or later we realize it is getting expensive for somebody and now that somebody is me. Now I'm full circle in my job as a machinist making gears to replace someone else's stripped gears. Ain't life funny? (Yeah, as long as somebody else is paying for it)
lol
Thank you for this video. I may have an opportunity to work with an Atlas lathe at a museum i want to volunteer at and found this video very informative.
👍👍👍
Absolutely wonderful video. I really appreciate your effort!
Thanks
"Always count numbers out loud"...I thought I was the only one that does this. My boss thinks I'm weird but if you have to walk across the room or climb down a ladder and you have 3 guys in the room talking about beer and chicken wings then saying it out loud makes all the difference between a finished product or scrap. Obviously if it's really important I can write it down, but over the course of the day you can lose a lot of time drawing pictures and writing numbers... bosses don't like that.
I love your videos, I have watched almost all of them, they are like "engineer porn". (LOL). I am building a lathe and I am almost done....I am waiting on my 5 inch chuck to come in the mail. Your videos have taught me a lot....mostly about thinking "smarter, not harder". Thank you!
Thanks for watching.--glad you like. Yes, the counting sure works for me.
when i was young and before i learned the right way to make gears i would trace a tooth from a gear .... hold a piece of paper to the tooth and make a rubbing with pencil or literally trace it... or xerox them.... i would cut the paper with a xacto glue to my blank then grind a cutter to fit with no light shining thru.... works great and i still do it that way unless i do not have a gear to copy
Great shot of cutting that last tooth!
Rod Rosenberg Thanks for watching
thanks very informative enjoyed watching
Wow, that was another great one. Watching these videos has really helped me with my career choices. I would most certainly be able to do the math, just not 8n a typical Vocational education setting.
You prolly dont care at all but does anybody know a method to get back into an instagram account?
I somehow lost my account password. I love any assistance you can give me.
@Seth Archie Instablaster :)
@Avery Cayden i really appreciate your reply. I got to the site through google and Im in the hacking process atm.
Looks like it's gonna take quite some time so I will get back to you later with my results.
@Avery Cayden it did the trick and I actually got access to my account again. I am so happy:D
Thank you so much you saved my account !
@Seth Archie Glad I could help :D
Very interesting video. I hope I will need this information to make gears one day.
+Arnljot Seem thanks for watching
Thanks for the help.
👍
Only piece of advise you left out is to make sure you wind the dividing head in the working direction to the first position to avoid the dreaded thin/thick tooth on the last cut, otherwise a fantastic and concise tutorial.
Ray Jones Thanks for watching
Thanks for sharing !
Great video I try and follow along 1-2 steps ahead to see if I get it correct on what and how the next step is done about 1/4 of the time I get it wrong lol but I am getting better! Looking forward to the next video and as always Thank you for taking the time- I really appreciate all that you do I have learned so much
Rosario W Thanks for watching
Great video! I have learned a lot with your videos on cutting gears. I ready to attempt cutting one of my own.

Nice job on the gear. Thanks for the review. Enjoyed. Thanks again. Randy
Randy Richard Thanks for watching
Great job!
Point of interest here, from the future lol. If you're buying cheap chinesium gear cutters like myself, they normally have the numbering system backwards. Meaning, a chinese DP16 14-1/2PA number 1 cutter will cut a 12 to 13 tooth gear, and so on. I don't know why this is the case, but i've found it to be true 100% percent of the time in my experience, which is very limited, but there you have it.
Thanks
Another great video, Mr Pete!
+Gordon Burns Thanks for watching
Mr. Pete, I mean no disrespect, but isn't 660 RPM way too fast for that cutter in steel? Mild steel should be cut around 100 SFPM or so, and with a cutter of 2.5" in diameter, that should be about 150 RPM. Or am I missing something?
That's the number my quick math check arrived at as well. Still, a good video on gear-cutting Mr Pete.. added it to my Favorites.
rock on Mr Pete
fantastic video. I learned so much from this
Thanks for watching.
Just watch Keith Fenner make a similar gear. The first is very expensive but the second one is almost free. Thanks for the videos!
Thanks for watching
I really enjoyed watching that, thanks!
lyle i mean... i dont know if you read this but I own a mini lathe for 3 months now and i'm about to build a real milling machine... i got the head and the knee almost completed and now i need to make a drive to couple my 1 hp induction motor to the spindle. i really want to use gears since its the most exact and the method with that i can put all the torque into the spindle, now i watch your video and i hope that after that i can make a set of gears that will fit (not a rich guy sadly :D ) so maybe you become part of my homebrew machine :)
You're an incredible guy!
Thank you
This is so much easier than my process of single point gear broaching on my lathe. You could single point broach the keyway on the mill or lathe with a HSS bit.
Thanks for watching.
You're a good teacher
I realize that this is a 7+ year old video (and I really enjoyed it), but at the 32 minute mark, where you're all finished cutting the gear and then remove the lathe dog and then the mandrel I wondered WHY?! I thought for sure you'd be taking the assembly back over to the lathe to do a final skim pass (and chamfer if you hadn't already) on both sides to clean them up. Seems that would be easier prettier than the belt sanding you suggest in the video, no? But again, I really enjoyed the video, and subscribed quite a while ago.
I enjoyed the video. Just one thought. after you find that you need 1/6th a turn on your turn wheel. you just need to find a plate that is dividable by 6. so a plate with 6, 12, 18, 24, 30, 36, etc
+mission772 good- THANKS FOR WATCHING
watched this video a few Times. One Day I will Make a gear lol. One day.
Great show! Thanks Sir!
I really wanted to see the broaching of the gear. I see them for sale every now and then.. I will be trying this.
Random guess: "Semi-steel" may mean that it was cast iron which was then steeled. You can do things like let it bake in a pile of charcoal until the carbon penetrates the outer layers, making a hard layer of steel around the iron core. It's easy, cheap and probably much faster to do in bulk at the time. Of course, I could also be completely wrong.
+Alex Osterman thanks for watching--could be
I know this is a stupid question but I'm finally getting around to doing this tomorrow so I noticed there's nine spaces in your 48 hole circle between dividing arms. So is that mean it's 9:00 because the first one is your first cut and then you move eight more and advance the arms?. I know this will be obvious to a lot of people but I'm very nervous
Enjoyed is exactly the word that describes what I did.....thank you
Thank you very much
I think it would be interesting if you built a wood lathe from scratch and showed how to make the parts and how to assemble one
+Jamesgamer88 Probably not, but thanks for watching

I have a montgomery wards 04tlc-700a that rattles something bad when running, what would you think it is. The rattle is coming from head stock at the bull gear.
I'd like to make some gears for a Logan that would allow metric threading through the quick-change gearbox.
MrShobar Thanks for watching
I did know (and love) Keith Rucker. Yet I didn't know about Keith Fenner. Thank you for that! TH-cam, more than half of what I watch is related to manual-operated machinery. Is it really so hard to figure this out and actually recommend popular channels like this that I don't know about? Sorry, I'm ranting, please ignore me.
